- Data Sheet
DetailsThese 6mm jets fit all Weber carbs. To set up the carb, start with an overlarge mainjet. This will cause the engine to missfire (fourstroke) on full throttle. You then gradually decrease the mainjet in size (in steps of 5) until the engine starts to run smoothly. Finetuning is then achieved by juggling around with the in-between sizes. Be careful: too small a mainjet will result in a lean mixture and piston seizures.
